Rmetrics VERSION 220.10064
2005-12-01 fSeries: GarchModelling
Major improvements could be achieved for the fSeries Package for GARCH
Modelling, although the GARCH modelling functions are still in an
experimental state and not yet finished.
2005-12-01 fCalendar: timeDate and timeSeries
A paper was submitted to JSS describing 'timeDate' and 'timeSeries'
Classes. A draft can be downloaded from www.rmetrics.org.
2005-12-01
Updates of the following files (if it was necessary) are now available:
CHANGES.html, COPYING.html, COPYRIGHT.html, FAQ.html, README.html
DocFactSheet.pdf, DocRefCard.pdf, DocRmetrics.pdf
________________________________________________________________________________
Rmetrics VERSION 220.10063
Rmetrics VERSION 211.10062
2005-11-02
This is a preliminary version with smaller modifications, updates, and
additions compared to Rmetrics 201.0061.
Not yet updated is the documentation included in DocFactSheet.pdf
Doc, DocRefcard.pdf, and DocRmetrics.pdf. These documents have Version
211.10062. This update is under progress.
The major effort was invested to make under both environments MS Windows
and Linux Rmetrics running based on the new compiler suite with
gfortran. Please note, that I have done this move for Rmetrics already
under MS Windows, although this is not yet done for R. The reason why
I have done this, is that I develop under MS Windows, and that I wan't
support two systems based on different compiler suites. The Mac Version
is not yet tested, but hopefully it will run without any problems.

The time Series class got a new slot named "@recordIDs". The
slot is represented by a data.frame whcih can be used for
data record identification. This may be useful for FX data
sets to name the contributor, to keep delays from the feed
or other information. For Futures this may for example name
the futures contract.
2005-04-28 fCalendar: C1-timeSeriesClass
The arguments named "colNames" have been changed to "units",

have been added.
2005-03-21 fPortfolio: A1-MultivariateDistribution
This is a collection and description of functions to compute
multivariate densities and probabilities from skew normal and
skew Student-t distribution functions. Furthermore, multivariate
random daviates can be generated, and for multivariate data,
the parameters of the underlying distribution can be estimated
by the maximum log-likelihood estimation.

is provided which allows for the selection and clustering of individual
assets from portfolios using hierarchical and k-means clustering
approaches.
2005-03-19 fPortfolio: A3-DrawdownStatistics

and random generation for the maximum drawdown distribution. In
addition the expectation of drawdowns for Brownian motion can be
computed.
2005-03-18 fPortfolio: B1-VaRModelling
This is a collection and description of functions to compute
Value-at-Risk and related risk measures for a portfolio of assets.
In addition utility functions are available to compute the maximum
loss, to calculate the total return, and to plot a histogram of
the total return.
2005-03-17 fPortfolio: B2-MarkowitzPortfolio
This is a collection and description of functions which investigate
the efficient frontier for a Markowitz portfolio from a given return
series \code{x} in the mean-variance sense when short selling is
forbidden. Tangency, equal weigths, and Monte Carlo portfolios can
also be evaluated.
2005-03-14 fPortfolio: B3-TwoAssetsPortfolio
This is a collection and description of functions which investigate
the efficient frontier for a two assets portfolio from a given return
series \code{x} in the mean-variance and CVaR sense when short selling

'logCobbDouglas' data for the Cobb-Douglas productivity function as
used in exaple 7.10 in the book of D.N. Gujarati; 'Greene4Table131'
US yearly investment data as listed in the book of W. Greene, 'pr45'
sales and durable goods data as used in the book of R.S. Pyndick and

C2-SkewGedDistribution have been merged to one, named C2-GarchDistributions.
C5-GarchDistributionFits has thus been renamed to C5-GarchDistributionFits.
2005-01-22 fBasics: HyperbolicDistribution
Functions to compute probability, density, quantiles and to generate
random deviates in 2nd, 3rd and 4th parameterization for the hyperbolic
distribution have been added. Furthermore, functions have been
implemented to compute the hyperbolic mode in all four parameterizations.

A function to compute the exponential of a square matrix has been
added.
2004-11-17 fSeries: fMultivar
The package 'fSeries' has become too "fat", so I partitioned it into
twp parts: 'fSeries' and 'fMultivar'. The first part now holds functions
for the analysis of time series including ARMA Modelling, GARCH
Modelling and Hypothesis Testing, the second part holds now functions
for time series anlaysis with regression methods and functions
for the technical anlaysis including rolling analysis and benchmarks.
2004-11-16 fBasics: B4-ClassicalTests/B5-StylizedFacts
The script file "B4-ClassicalTests" has become too big, so we divided
them into three new parts named "B4-TestsClass", "B5-OneSampleTests",
and "B6-TwoSampleTests". The script file "B5-StylizedFacts" has been
renamed "B7-StylizedFacts". This information is given for those who
are interested in the source code and internal structure of the Rmetrics
packages.
2004-11-14 fBasics: ClassicalTests
We made some changes on the classical test functions. We have
introduced an S4 object of class "fHTEST" which describes the
classical tests, we have added the usual arguments "title" and
"description" to the argument list, and the output of the test
now gives more information than the typical printing of R's S3
object "htest".
2004-11-13 fBasics: SPlusCompatibility
These are R functions which we made available for SPlus, including
- General Functions: strsplit, match.fun, cov, forwardsolve, %x%,
data, NROW, NCOL, sd, nlm, optim, download.file.
- Tests: bartlett.test, fligner.test, kruskal.test.
These functions may be helpful for porting Rmetrics functions
to SPlus.
2004-11-11 fSeries: garchSim
The function "garchSim" was not working properly when not all model
parameters where explicitely specified in the argument list.
Missing parameters are now added correctly. [Note, that the "garch"
functions will be replaced soon by a new completely rewritten
package in the near future.]
2004-10-29 fExtremes: gpdFit
The residual statistics and the information about threshold value
and the number of exceedances have been added to the summary report.
Now, beside numeric vectors also univariate time series objects
are accepted as input arguments.

Now, beside numeric vectors also univariate time series objects
are accepted as input arguments.
2004-10-29 fExtremes: gevFit

Now, beside numeric vectors also univariate time series objects
are accepted as input arguments.
2004-10-29 fExtremes: gevglmFit
The residual statistics has been added to the summary report.
Now, beside numeric vectors also univariate time series objects
are accepted as input arguments.
2004-10-27 fExtremes: data/*
The "bmw", "danish" and "siemens" data are now 2 column data frame
objects with the first column as ISO-8601 character dates %Y-%m-%d
and the second column as numeric values. Formerly they were numeric
vectors with POSIX date attributes. Now these data records can
easily be transformed to 'timeSeries' objects and used in the same
way as under SPlus.
2004-10-16 fOptions: xmpfOptions
Bug removed. Internal function 'readf.fOptions00Index' corrected
as '.readf.fOptions00Index'. Now the fOptions examples should work.
2004-10-16 fOptions: BesselFunctions
Modified Bessel Functions of the first and second kind for integer
order together with their derivatives have been added. The functions
are entirely written in S.
2004-10-14 fOptions: EBMDistribution
Examples have been added to the help file. In addition a bug was
fixed: An internal used variable for the computation of the second
derivative of the reciprocal Gamma and Johnson Type I distribution
was missing.
+ many other smaller improvements and fixings ...

Three new Chapters have been introduced with functions to compute
distributions, the error, gamma and related functions, and the
confluent hypergeometric functions. These functions are useful in the
field of Exponential Brownian Motion and for the valuation of
Asian Options. The demo file "demo/funOptions.R" where the functions
where originally listed is now obsolete.
2004-09-14 fSeries: UnitrootDistribution
Two functions to compute the cumulative probability, punitroot,
and the quantiles, qunitroot, of the unit root test statistics

2004-09-03 fSeries: EquationsModelling
We have added functions to perform fits of systems of regression
equations. The underlying functions are those from the contributed
R-package 'systemfit' written by Jeff D. Hamann and Arne Henningsen.
'systemfit' offers functions for fitting linear structural equations
using Ordinary Least Squares (OLS), Weighted Least Squares (WLS),
Seemingly Unrelated Regression (SUR), Two-Stage Least Squares (2SLS),
Weighted Two-Stage Least Squares (W2SLS) or Three-Stage Least
Squares (3SLS). The wrapper fullfills the naming conventions of
Rmetrics, returns a S4 objects, and allows for 'timeSeries' objects
as input. In addition a S-Plus like Finmetrics function 'SUR' is
made available.
2004-09-03 fSeries: xmpEqnsGreenfeld
An example to estimate Grunfeld's Model Data with OLS and SUR was
added. Different stock prices often move in the same direction at
a given point in time. The SUR technique may provide more efficient
estimates than OLS in this situation. The example was used by Zellner
in his classic. 1962 paper on seemingly unrelated regressions.
2004-09-03 fSeries: kmenta.csv
A data file which contains partly contrived data from Kmenta (1986) has
been added, constructed to illustrate estimation of a simultaneous
equation models.
2004-09-02 fBasics: HolidayCalendars
The function 'fjulian' got a new argument 'swap' making the old
one 'cc' obsolute. This change was inspired by the POSIX standard.
'swap' is an integer value which determines when dates without
the century specifications swap from the 19th to 20th century,
by default the value is 20, i.e. we swap 1920.
2004-09-02 fBasics: WebImport
A new function named 'fredImport' has been added which allows for
downloading daily financial market data from the St. Louis FED.
The import functions got a new argument 'sep' which allows to
specify the field separator in the data file, usually an Excel
*.csv file. The default is a semicolon.
2004-08-05 fSeries: DESCRIPTION
The package 'modreg' has been merged into 'stats', so we have
removed it from the dependency list in the description file.
This caused for Mac OSX operated system a failure.
2004-08-05 fSeries: surex1.ts.csv
A data file has been added which contains monthly sampled exchange
rate spot returns and forward premium data ranging from March 1976 to
June 1996 for the following currencies: USD vs. CAD, DEM, FFR, ITL,

The three demos "xmpImportYahoo", "xmpImportEconomagics", and
"xmpImportForecasts" have been merged to one new demo named
"xmpImportInternet" to reduce a little bit the large number of
example files.
2004-07-07 fBasics: xmpXtsBusinessTime
The four demos "xmpXtsDailyWeeklyHists", "xmpXtsInterpolation",
"xmpXtsDeSeasonalization", and "xmpXtsDeVolatilization" have been
merged to one new demo named "xmpXtsBusinessTime" to reduce a
little bit the large number of example files.
+ many other smaller improvements and fixings ...
